To a/ZZ whom it Wto/y concern:

Be it known that we, ARTHUR T. HAGEN and DANIEL M. COOPER, of Rochester,county of Monroe, and State of New York, have invented certain new anduseful Improvements in Driers; and we do hereby declare the following tobe a full, clear, and eXact description of the same, reference being hadto the accompanying drawings, forminga `part of Io this specication, andto the figures ofreference marked thereon. y r Our present invention'has for its object to provide a drier of the endless-conveyer type lparticularly adapted for carrying small arti-` 3o in the claims'at theend of thespecication. In the accompanying drawings, Figure l is a planview, partially in section, of Athe portion of a drier embodying ourimprovements. l Fig. 2 is a perspective` View of aportion of f theconveyer, showing the clutch-operating mechanism and the holder orhanger for the articles being dried. Fig. 3 is avertical lon-` gitudinalsection of one of thecarriers, showing the doer; Fig. 4, asectional View`on the,V 4o line a a of Fig. 3; Fig. 5, a section on the] line b b ofFig. 1; Fig. 6, a similar View on Athe line c c of Fig. 1.

Similar reference-numerals in the several figures indicate similarparts.

Referring particularly to Figs. 1 and `6, 1 isa drying room or apartmentof any suitable dimensions and heated by any suitable means, such assteam-coils, the air therein being caused to circulate, if desired, by afan or blower of any suitable construction. Arranged within this chamber1 is a suitable track 2, preferably tubular in form and having a slot atthe bottom for the passage of Shanks or projections 3, having at theirupper ends rollers 4, operating on the4 lower horizontally-extendingflanges of the track 2, as shown particularly in Fig. 2, the lower endsof the Shanks or projections 3 being attached at intervals to an endlessconveyer or sprocket-chain 5, supported below the track 4by said shanks,and said conveyer or chain extends around guide-wheels arranged at thebends, angles, or curves of the track andbelow the same for the purposeof guiding the conveyer in its passage into, through, and externally ofthe drying-chamber. The dryingehamber is provided with the aperture 50,into and out of which the conveyer passes for carrying the articlesto bedried into and from the chamber, and some of the guidewheels for theconveyer and portions of the track are supported outside of the chamber,so that the articles carried by the conveyer may be applied to andremoved from the latter at the exterior. The conveyer may consist of anordinary sprocket-chain driven at one or more points, if desired, bypower applied to the sprocket-wheels engaging it, and in the located atthe ends of the conveyer-loops in the 'chamber and attached tovertically-extending 'shafts 6,A having at their upper ends beveledgears 7, with which'mesh corresponding pinions 8, secured to ahorizontally-extending `shaft 9, arranged above the chamber,as shown inFigs. 1 and 5. `The shaft 9 is ,adapted to be driven by acontinuouslyQrotating drivingshaft 10 through a suitable clutch connection, `that shown in the present instance eu1- bodying a section 11,secured to the shaft 9,

and a movable section 12, operated bya suitable shifting lever 13, thefree end of which is attached to a cord or chain 14, extending aroundsuitable guide pulleys 15 and attached to one end of a lever 16,pivoteld to a bracket 17 on an extension or'support 18. The leve`r`16 isprovided at one end with a counterweight 19 and with a downwardlyexpresent instance we have provided two Wheels tending arm 20, arranged inproximity to the conveyer outside of the drying-chamber and adapted tobe engaged by a suitable projection on the conveyer for the purpose ofoperating the lever and disconnecting the clutch when desired.

For the purpose of actuating the clutchsections into engagement the endof the chain 14 may be extended beyond the lever 13, as

indicated at 114, Fig. 1, and provided with any suitableoperating-handle 140, by means of which the lever 13 may be moved in theopposite direction from that in which itis operated by the lever 16.

As stated', the conveyer may consist of an ordinary sprocket-chain, thelinks of which A are connected in the usualmannemand atsuitableintervals some of these links are provided wi th downWardly-extending shanks 2l,

.preferably threaded, as shown in Figs. 3 and 4, and carrying at theirlower ends arms or carriers 22, screwing upon the threaded portions ofthe Shanks and secured from turning by suitable means, suchas a pin 23.The lower ends of the carriers 22 are extended laterally of the conveyerand are provided with pins or projections 23, curved or inclined at aslight angle from the horizontal and extending in planes substantiallyparallel with the conveyer for the purpose ot' supporting the articlesto be dried.

24indicatesa stripper pivoted upon the carrier 22, preferably near itsupper portion and having at its lower end perforations through whichAthe supporting-pins 23 extend, said strippers in the present instancebeing formed of a single plate of metal having perforated ears at itsupper portion forming journals and in the present construction hangingloosely upon a sleeve 25, passing laterally through the carrier 22. Thestrippers are provided above their pivotal points with arms l orextensions 26, formed integrally with a plate and adapted to be engagedby a stationary arm or projection 27, secured to the support. 18,arranged in the path of the projections26 and at one side of theconveyer.

The projection or projections upon the conveyer for operating theclutch-controlling lever 16 may be of suitable construction and capableof application to the conveyer at different points, and in the presentinstance these are in the form of removable stops or Y pins 30, adaptedto be inserted in suitable `ing mechanism.

ber, and they are then carried by the conveyer into the drying-chamberthrough the aperture 50 and back and forth therein any desired number oftimes and finally pass out of the aperture 50 to the exterior. As thecarriers 22 pass beneath the projection or arm 27 the upper ends 26 ofthe strippers will be engaged therebyand the strippers tilted to theposition shown in dotted lines in Fig. 3, stripping the articles fromthe supportingpins 23 and allowing them to drop into a suitablereceptacle placed beneath. When it is desired to arrest the operation ofthe conveyer-as, for instance, when one carrier has made a completecircuit of the drying-chamber-the pin 30 is inserted in the recess in`the carrier which is to be arrested, and when this pin engages the arm2O of the lever 16 the latter will be tilted and, drawing upon theflexible connection 14, will operate the movable clutch-section anddisconnect the driv- By providing means whereby the driving mechanismcan be disconnected from the conveyer when any of the supports reach apredetermined position the operators applying the articles may cause thestoppage of the mechanism as often as desired during its passage throughthe dryingchamber in order to permit the separate lots of articles to bedeposited in different receptacles arranged beneath thestripper-operating cam, a change of receptacles being elected during thestoppage of the conveyer.

We find in practice that by arranging a separate positively-actuatedstripper upon each of the supports attached to the conveyer, eachstripper moving in close proximity to the supporting-pins 23, thearticles will be positively removed and cannot become fastened to thepins by the drying starch.

We claim as our invention- 1. The combination with a track, a conveyertraveling on the track and the carrying-pin thereon, of a stripper onthe conveyer movable longitudinally of the carrying-pin.

2. The combination with a traveling conveyer and the carrying-pinthereon, of a stripper on the conveyer movable longitudinally of the pinand stationary means for engaging and operating the stripper. j

3. The combination with a traveling conveyer and the carrying-pinthereon extending longitudinally of the conveyer, of a stripper on theconveyer movable longitudinally of the pin for removing articlestherefrom and a stationary projection for engaging and moving thestripper.
